Josh thinks an old gay man would murder to get with a younger straight Christian guy?
		
		
	 
 Null as a homophobe expects gay men to be either useless (because they're not masculine), gross (because they are sex maniacs/degenerates) or outright dangerous to straight people (because be gay do crimes). He thus expects a movie about a fat dying gay man to be, not about the gay man's own death, but about confirming whatever stereotypes Null has of gay men being a threat to normalcy. Null expects the gay character to murder 
"a good young Christian man" (has Null seen Bones and All?), but when that stereotype isn't confirmed and that murder doesn't happen, Null is disappointed because the film challenges his stereotypical way of thinking. 
BTW, this death wish directly contradicts what Null claims towards the end of his review, claiming that he expected this to be a movie where the gay lead decides change his life around and to better himself, which also doesn't happen (Null has clearly never seen an Aronofsky movie before, AFAIK his movies never have such neat endings or resolutions). Null apparently doesn't even see how this expectation of self-improvement directly contradicts the negative stereotype of a gay man who murders good Christians, which Null also expected to be confirmed in this film. Null's homophobia is like a Catch 22: he expects gay characters in film to "self-improve", at the same time as he expects them to be the worst, most dangerous of criminals.
What I found most amusing about Null's review was him admitting that he cannot relate to the film's theme of honesty. When you spend most your days trad-LARPing on the internet, running your mouth about the Bible when IRL you can't even maintain a Lent fast (cos these trad-LARP hypocrites can never live up to their professed religious standards, it's all talk), then I suppose the concept of "honesty" is quite alien to you indeed. 
For those of your who haven't seen 
The Whale and don't mind spoilers, this is the scene he was referring to:
I also LMAO at Null saying he didn't like the character of the daughter because she is "cruel": 
"I'm a smart person. I never forget anything. You'd be disgusting even if you weren't this fat. You'd still be that piece of shit dad who walked out on me when I was 8, all because he wanted to fuck one of his students.".

How does Null not like this scene? This is literally the hatred that Null and his forum expect the kids of LGBT parents to grow up having towards their parents.
